COMBINED LOCK AND LATCH'.

IEZECIFIUATZON forming part of Letters Patent No. 308,559, datedNovember 25, 1884.

`xpplication tiled February 27, 18F4.

T all whom it may concern:

Be it known that I, Hormon L. HEATON, a citizen of the United States,and a resident of Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in Door Locksand Latches; and I do hereby declare that the following is afull, clear,and exact description of the invention, which will enable others skilled1o in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecication, and in which- Figure l is a side view of my improved latchand lock. Fig. 2 is a similar view of the same with one side cf thecasing removed. Fig. 3 is a horizontal section on line x x, Fig. l. Fig.4 is a similar View online y y, Fig. l; and Fig. 5 is a detail view ofthe tumbler.

Similar letters of reference indicate corresponding parts in all theiigures.

My invention has relation to that class of locks and latches in which agravitating arm connected to the lock-spindle and having a projectinglug engages a notch in the main bolt, with the said lug forcing itoutward, and in which a tumbler operated by the key may engageprojections or shoulders upon the main bolt, locking the same; and itconsists in the `@,oiinproved construction and combination of parts ofsuch a lock and latch, consisting of a gravita-ting bolt pivoted uponthe lock-spindleand engaging a notch in the main bolt by anupwardly-projecting lug, and of a sliding tumbler adapted to be operatedby the key,

and to bear against a shoulder at the outer portion of the main bolt, ashereinafter more fully described and claimed.

In the accompanying drawings, the letter A 4o indicates the lock-casing,which may be constructed so as to be secured upon either side of thedoor or to be inserted into a niortise,

as desired, and the main bolt B slides with its outer end, which may besquare orl beveled,

as desired, in a slot, C, in t-he forward side of the lock-casing, andslides with its inner portion upon a lug, D, projecting into alongitudinal slot, E, in the inner portion of the bolt. The forward orouter end of the bolt (No model.)

forms shoulders F, the inner portion of the 5o bolt, or the portionwithin the casing, being reduced, and the rear end of the bolt has twonotches or recesses, G, one extending from each edge. Anupwardly-projecting lug, H, projecting from the inner portion of agravi- 5 5 rating arm, l, pivoted within the casing, pro jects into thenotch or recess upon the lower edge of the bolt, and the weight of theforwardly-projecting arm will force the lug, and through it the bolt,forward. The gravitat- 6o ing arm forms at its fulcrum two laterallyprojecting round lugs, J, which project through and turn in perforationsK in the sides of the loclccasing, and the lugs and the end of the arinfrom which they project have a perforation, L, preferably square,through which a correspondingly-shaped lug, M, projecting inward fromthe end of an arm, N, projects and fits. This lug has a central femalethreaded perforation, O, into which the 7o inner threaded end, P, of thespindle Q fits and turns, and the said threaded end of the spindle isprevented from turning in its perforation when screwed home by means ofa screw,

R, passing through a threaded perforation, S, 7 5 in the arm and lugeccentric to the other perforation, -but entering the side of the saidperforation; and the threaded end of the spindle has acorrespondinglythreaded groove or recess, T, at the side facing theportion of its per- 8o foration opening into the other perforation,

so that the securingscrew R fits partly in its perforation in the armand the lug and partly in the threaded groove in the end ofthe spindle.The other side of the threaded perforation S S5 for the securing-screwis also open, and the adjoining side of the square perforation in thegravitating arm has a groove or recess, U, having a portion of ascrew-thread corresponding to the thread of the perforation, and thesecur- 9o ing screw will thus bind the spindle, the gravitating arm, andthe inwardly-projecting square lug together. I wish, however, to statethat the spindle or operating-arm may be connected to the gravit-atingarm in any other 9 5 -suitable manner without departing from the spiritof my invention.

V is a tumbler having a reduced rear or i11- ner end, V, which slidesupon a stud, X, pro- -ieeting from the inner side of the casing, and theforward or outer portion of the tumbler is en1arged,as shown at Y, andhas a longitudinal slot, Z, having two notches, A', one at each end, andhas a notch or recess, B', in its lower end, in which the bit of a key,C', may engage, raising the tumbler and causing one of the notches inthe slot to be raised off a stud, D', upon the inner side of the casing,upon which stud the slot slides, thus allowing the bit of the key toslide the tumbler. The forward end of the tumbler may, when the tumbleris slid forward, be brought to bear against one of the shoulders uponthe sides of the bolt, thus preventing the bolt from being drawn inward,the bolt being reversible, so as to bring its beveled side, when it isbeveled, to either side. An arm, E', may be secured to the upper edge ofthe tumbler, projecting up through a slot, F', in the upper side of thecasing, by means of which arm the tumbler may be operated, and when thisarm is used a catch, G', may be pivoted upon the upper side of thecasing, turning,withits downwardly-projecting lug H', in a slot orperforation, I', and may be brought to bear against the upper end of thearm, when the latter is thrown in its forward position, preventing thearm from being thrown back, and through it preventing the tumbler frombeing slid back, thus forming a dead-latch. The inner side of the lowerside piece of the casing is provided with a rubber or other elasticcushion or spring, against which the weighted arm may bear when tilteddown. It follows that the forwardly-projecting weighted portion of thegravitating arm may be dispensed with and the operating-arm may beweighted in its place, Vand that the relative position of the lu'gprojecting into the notch in the bolt and of the weighted arm may bechanged accord-` ing to the direction in which the bolt is to be forcedand according to the position of the casing.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. The combination, in a lock, of abolt having its inner end reduced, forming shoulders at its outer end,and having a notch in its edge, a gravitating arm having a lugprojecting into the notch,and having means for rocking it, and a tumblerhaving a longitudinal slot forming notches in both ends and sliding upona pin,and having means for throwing it forward, bearing against thcshoulder of the bolt, as and for the purpose shown and set forth.

2. In a'lock and latch, the combination of a sliding bolt having itsinner portion reduced, forming shoulders at its outer portion, andhaving notches in the rear ends of its edges, a gravitating arm having alug engaging one of the notch es in the bolt, and having means forrocking it, and a tumbler sliding,with a longitudinal slot formingnotches at both ends, upon a pin, and having a notch or recess in itslower edge for the bit of the key adapted to be thrown forward to bearagainst one of the shoulders of the bolt, locking it, as and for thepurpose shown and set forth.

3. In a lock and latch, the combination of a sliding bolt having itsinner portion reduced, forming shoulders at its outer end, andhavinggnotches in the rear ends of its edges, aA

gravitating arm having a lug engaging one of the notches in the bolt,and having laterallyY projecting tru unions at one end turning in thelock-casing, and provided with an operatingarm and with a handle, and atumbler sliding, with a longitudinal` slot forming notches at bothends,upon a pin having a notch or recess in its lower edge, and providedwith an arm secured to its upper edge and projecting through the upperside of the casing.

4t. IThe combination of the gravitating arm having trunnions rocking inthe sides of the easing, the said trunnions having a square perforationwith a threaded groove in one side, an operating-arm having a square lugfitting into the perforation, and having a cen- -tral threadedperforation entering it at its inner end, and an eccentric threadedperforation opening at one side into the central perforation and at theother side into the groove in the square perforation, a spindle havingits inner threaded end fitting into the central threaded perforation,and having a threaded groove in one side, and a securing-screw passingthrough the eccentric perforation and tting into the female threadedgrooves in the end of the spindle and in the square perforation, as andfor the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
